SAW-SET.

Specification of Letters Patent.

Patented May 8, 1906.

Application filed June 29, 1905. Serial No. 267,609.

To all whom it may concern:

Be it known that I, HARRY WISE, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented a new and useful Saw-Set, of which the following is a specification.

This invention relates to saw-sets, and especially to those saw-sets adapted and arranged to set two ormore teeth at the same time and from opposite sides.

The object of this invention is to provide a saw-set having movable anvils arranged to clamp the saw-blade therebetween and to hold the blade in such position while the teeth are being given the desired curvature.

A further object of the invention is to provide a saw-set the setting-plungers of which may be moved longitudinally relative to each other to adapt the set for use in connection with saws of different gage.

A further object of the invention is to provide a saw-set having a movable guide adapted for use in connection with the plungers operating from opposite sides andby the use of which the point of contact between the plungers and the teeth may be accurately adjusted.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as willbe hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made Within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accom anying drawings, Figure 1 is a view in side e evation of the im roved sawset forming the subject-matter this invention and with the side covering-plate broken away to show the mounting of the several levers. Fig. 2 is a view in end elevation of the saw-set with a portion of the upper jaw broken away to show the manner of mounting the springs. Fig. 3 is a transverse sectional view of the jaws and head of the sawset, taken on line 3 3 of Fig. 2. Fig. 4is a bottom plan view of thelower jaw and sawguide, exhibiting the manner of adjusting the guide. Fig. is an enlarged detail sectional view of the anvils and p ungers, showing a saw-blade therebetween and two teeth setin opposite directions. Fig. 6 is a longitudinal sectional view taken on the line 6 6 of Fig. 2, showing the manner of mounting the anvil on the lower jaw.

Like characters of reference designate corresponding parts in each and every figure of the drawings.

In its preferred embodiment this invention comprises a handle 1 andahead 2, rigid therewith. Upon the head 2 is pivotally mounted a handle 3 by the pin 4 and having an end 5 extending beyond the pivot 4 and provided upon opposite sides with cam-faces 6 and 7. Upon the head 1 are mounted the jaws 8 and 9 by the pins 10 and 11, respectively. The jaw 8 is provided with a lever extension 12 engaging the cam-face 6 of the handle extension 5, and the jaw 9 has a cam-face 13 engaging the cam-face 7. To hold the jaws normally open, a spring 14 is disposed between the jaws, and to limit the closing movement of the jaws a screw 15 is mounted in the handle 1 and for engagement with the handle 3.

The jaws 8 and 9-are provided, respectively, with transverse openings 16 and 17, which open through the adjacent faces of the jaws, as indicated at 16, and within which are mounted anvils 18 and 19, respectively, the latter being provided with flanges 20 and 21, which engage the inwardly-extending lips 17 and revent accidental displacement of the anvil s but permit a limited vertical movement of the latter within the openings 16. The anvils are provided with transverse 0 enings 22, formed in the backs thereof anol extending throughout a portion of their widths and in which are mounted springs 23, bearing against the jaws 8 and 9 and holding the anvils with the flanges 20and 21 normally in contact with the lips of openings 6 and 17. Adjacent the transverse middle line the anvils are provided with transverse bores 24, within which are mounted plungers 25 and 26, bearing at their inner ends against the internal walls of openings 16 and 17 and extending through the face of the anvils and terminating in beveled ends 27 and 28. To hold the plungers normally in contact with the interior walls of the jaws 8 and 9, springs 29 are provided, surrounding the plunger and bearing against the lower extremities of the bores 24 and against heads 30 and 31, formed upon the plungers.

To adust the plungers for contact with sawadjustment.

teeth at desired points, a guide is provided, comprising a plate 32, carrying upstanding arms 33, provided with right-angularly-disposed flanges 34 for contact with the extremities of the saw-teeth. The guide is regulated by loosening screws 35, disposed within slots 36 and engaging the jaw 9. To adjust the plungers to saw teeth of different gages, screws 37 and 38 are provided, piercing'the arms 33 and contacting with the ends of the anvil 19. To prevent the longitudinal displacement of anvil 18, a plate 39 is provided, having lips 40, downwardly disposed at each end over the jaw 8 and secured in any approved manner, as by the screw 41.

In operation the saw-set is placed over the toothed ed e of a saw until the plates 34 contact with t e extremities of the teeth. The screws 35 are then loosened and the guide moved transversely to such position that the plungers contact with the teeth at the desired points, after which the screws 35 are tightened to retain the guide at the desired The anvil 19 is then adjusted to operate with the gage of saw required by loosening screw 37 or 38 and tightening the opposite screw, thereby movin the anvil 19 and the plunger 26 transverse y of the jaw and to a position such that the points 27 and 28 of the plungers will contact squarely with adjacent teeth upon opposite sides. When the desired adjustments have been secured, the handle member 3 is forced downwardly toward the handle member 1, thereby operating the jaws 8 and 9 to force them together and to force the anvils 18 and 19 to clamp opposite sides of a saw-blade, as indicated more especially in Fig. 5. When the anvils have contacted with the saw, a continued pressure upon the handle will cause the jaws 8 and 9 to force the plungers 25 and 26 downwardly through the anvils and against the saw-teeth, and a continued pressure will bend the teeth to conform to the beveled ends 27 and 28, thereby producing the desired set of the two teeth in opposite directions,

Having thus described the invention, what is claimed is- 1. A saw-set embodying cooperatin yieldably-supported anvils, cooperating p ungers carried by the anvils, abutments adapted to engage the plungers, means for adjusting one anvil longitudinally, with respect to the other, and means for forcing the anvils together.
